7 QMMQN VENTOR ATTORNEY y Y JOSEPH BUDICK, or AKRON, onto.

To aZZ whomz't may concern:

Be it known that I, JosErH Bunion, a citizen of the United States, residin at Akron, in the county of Summit and tate of Ohio, have invented new and useful Improvements in Mutes, of which the following is a specification. I r

This invention relates to certain new and useful improvements in mutes for cornets, trombones and the like.

Objects of the invention are to provlde a mute, of simple, inexpensive construction which in use, will provide efiicient means whereby the sound produced by a wind blown instrument may be muflied.

A further object is to provide a mute of the type indicated which is constructed with movable and interchangeable parts which may be selectively employed to secure certain changes in sound and to thereby provide a mute which may beused to secure various results. i

Th above and additional objects are ac complished by thenovel construction, combination and arrangement of parts herein,- after described and shown in the accompanying drawing, wherein I have illustrated a preferred embodiment of the invention, it being understood that the invention is capable of various adaptations and that changes and variations may be made or substitutions resorted to which come within the scope of the claim hereunto appended.

In the drawing in which similar numerals of reference have. been employed to indicate the same or similar parts as they appear in the several views Figure 1 is a side elevation of a mute constructed in accordance with this invention showing the same with the end disk removed.

Figure 2 is a cross sectional view taken as indicated by the line 2-2 of Figure 1.

Figure 3 is a central longitudinal sectional view of same taken as indicated by the lines 3-3 of Figure 1.

Figure 4 is a plan view of one of the vibratory inserts for the end disk.

Figure 5 is a central sectional view of same taken as indicated by the line 5-5 of Fi ure 4.

*igure 6 is a plan view of the end disk or lid of my improved device.

Figure 7 is a central sectional view of same taken as indicated by the line 7-( of Figure 6. y

end disk which maybe. used in carrying out the invention. v M a I Figure 9 is a cross sectional view of same taken as indicated by the line 99 of Figure 8.

A device constructed in accordance with this lnvention comprises a body portion 10 having the form of a hollow truncated cone, the wall of which is extended at the larger end in the form of a relatively short cylindrical portion 11 which is externally threaded with the screw'threads 12. The body 10 is composed of hard rubber, but may be composed of any suitable material and is provided on its exterior surface adjacent the small end thereof with a plurality of longitudinally directed ribs 13 which are composed of cork or other suitable material adhesively or otherwise secured thereto so 75 regularly re as to be positioned thereon at curring intervals.

The numeral 14 is used to denote the end disk or lid which comprises an internally threaded cylindrical member having an end wall 15. The end wall 15 is provided with a plurality of circular openings or bores 16, each of which is counterbored on the interior face of the wall 15 to provide a seat 17. The numeral 18 indicates an insert which comprises a ring adapted to fit in said seat. A vibratory diaphragm 19 of parchment or other strong, thin material is adhesively secured toone side of the ring 18 so as to completely close the opening in said ring. Each insert 18 is suitabl secured in one of the seats 17 with the diaphragm 19 presented outwardly. V

In Figures 8 and 9 I have illustrated a lid 14; which is similar to the said lid or disk described, diflering therefrom by having a solid wall 15.

OFFICE. I

In use the lid 14: is threaded on the end 12 of the body 10 and the said body portion 10 is inserted in the bell of a wind blown instrument with suifcient force to cause a compression of the ribs 13 and the device is thus held in position in said bell. When used in this manner, my improved mute not only provides means for mufliing the tone, but

sound is produced by the diaphragm 19 of the inserts 18 resulting in a tone which adds a certain novelty to the music produced by the use of said instrument.

If desired the lid 14 which has a solid end wall 15 may be threaded on the end 12 of the body 10 and used as above set forth, in which case an unusually clear, subdued.

tone may be produced.

teriorly threaded relatively short cylindricl l portion and a lid having an end Wall and interiorly threaded cylindrical side Wall adapted to fit over said cylindrical portion, openings in said lid, an insert in each opening, each insert comprising a ring and a thin, strong diaphragm stretched over the opening in said ring substantially as and 20 for the purposes herein set forth.

In testimony whereof I have hereunto set my hand.

JOSEPH RUDIGK.
